Latest vehicles are increasingly equipped with new technologies, apart from the comfort of use it can provide, technology as well has the advantage of saving fuel or reducing the pollution emitted by our vehicles. This is exactly the subject matter of our content page of the day, we are going to look at the problems of the lambda sensor on Land Rover Discovery Sport , this sensor as well known as oxygen sensor plays an necessary function. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor problems on Land Rover Discovery Sport and how to resolve them.
What is a lambda fonction on Land Rover Discovery Sport?
So we start our content with the interest of a lambda sensor on Land Rover Discovery Sport , we will first discover what is the task of this probe and then how it functions.
Role of a lambda sensor on Land Rover Discovery Sport
First designed by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Land Rover Discovery Sport , its task is to regulate the amount of oxygen in the exhaust gases, this will allow the engine unit to change the air/fuel mixture to reduce the pollution emitted by the motor vehicle and reduce the car’s fuel consumption.
Lambda sensor procedure on Land Rover Discovery Sport
Before describing you the different problems of lambda probe on Land Rover Discovery Sport , we will look a little more in outline at its working to allow you to figure out exactly how it functions and thus to consider more serenely the correction of a problem related to it.
As we informed you, a lambda probe has the task of managing the amount of oxygen present in the exhaust gases . One could naively think that this data is measured upstream of the combustion but it is on the contrary measured at the engine outlet . With the EURO 1 standard there was just one lambda sensor required before the catalyst, but with the arrival of more drastic requirements there are now 2 lambda sensors, one before and one after the catalyst . The interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will adjust the quantity of air and gasoline inserted into the engine unit to optimize the combustion .

.
Finally, we are now going to attack the part you are certainly most keen on this content, how to proceed if you have a lambda sensor problem on Land Rover Discovery Sport . In a first step we will see how to identify a lambda sensor HS and in a second step how to change it.
How to know if a lambda sensor on Land Rover Discovery Sport is HS
.
It is necessary to know that a lambda sensor has generally a lifetime of 150 000 km , this info can fluctuate according to the year of your Land Rover Discovery Sport, your driving, and the good working of your engine unit. A poorly maintained engine unit that emits unburned gases may permanently corrupt your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Land Rover Discovery Sport may be the engine unit light comes on, if you want to turn off the engine light of your Land Rover Discovery Sport, do not hesitate to visit our dedicated content to discover the procedure to stick to. The only effective technique to be sure that you have a lambda sensor problem on your Land Rover Discovery Sport and to pass your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Land Rover Discovery Sporthow to read the fault code of a Land Rover Discovery Sport. Please be aware that if you have problems with one of your lambda sensors, the just remedy to correct them will be to change the faulty sensor.
How to change a lambda sensor on Land Rover Discovery Sport?
And finally, we are going to focus on the correction of lambda sensor problems on Land Rover Discovery Sport , by explaining how to replace a lambda sensor.
The replacement of a lambda sensor is quite very easy to accomplish and you will have the ability to do it yourself with a minimum of tools and mechanical know-how. A lambda sensor is worth between 25 and 50€ , it is better to change the 2 lambda sensors present upstream and downstream of your catalytic converter because if one of them is faulty the second one risks to drop you fairly quickly. To replace it, it will be required to put your Land Rover Discovery Sport on candles and at the level of your catalyst unscrew your probes, disconnect them, reconnect them and screw the new ones . Once re-connected, you should not have any more problems with your lambda sensor on Land Rover Discovery Sport.
